ASP.NET is not authorized to access
the requested resource. Consider
granting access rights to the resource
to the ASP.NET request identity.
ASP.NET has a base process identity
(typically {MACHINE}\ASPNET on IIS 5
or Network Service on IIS 6) that is
used if the application is not
impersonating. If the application is
impersonating via , the identity
will be the anonymous user (typically
IUSR_MACHINENAME) or the authenticated
request user.

To grant ASP.NET access to a file,
right-click the file in Explorer,
choose "Properties" and select the
Security tab. Click "Add" to add the
appropriate user or group. Highlight
the ASP.NET account, and check the
boxes for the desired access.
